How does the shore power converter work on a camper?

Put another way, the 12-volt converter takes the 120-volt shore power, converts it to 12 volts, and then supplies DC power to everything in the camper irrespective of the battery disconnect switch. The difference is that when the switch is turned “on”, the converter charges the batteries; when it’s turned “off” it does not charge the batteries.
